Raul Rosas Jr. started training when he was four years old , first “just for fun” before taking it seriously after watching his dad fight. Another account says he later said he began training at 17 after being bullied, but his official UFC bio and an ESPN profile both point to age four as the start of his fighting training.

Quick Scoop

  • Primary answer: age 4.
  • How it began: he watched his father train, then started karate and later expanded into other martial arts.
  • Why there’s confusion: some later interviews repeat a different “started training at 17” claim, likely referring to a more serious or changed phase of training rather than his original start.

What the sources say

The UFC bio states: “I started training when I was four, just for fun,” and says he became serious after seeing his dad fight around that age.

ESPN also reports that at 4 years old he began watching his father train, then started karate and other disciplines, which fits the same timeline.

A separate later article quotes Rosas Jr. saying he started training at 17 because he was bullied, but that conflicts with the UFC and ESPN accounts, so it’s best treated as a later-stage or inconsistent statement rather than the clearest starting point.

If you mean when he first began martial arts/fighting , the answer is around age 4. If you mean when he became serious about training , some later reporting points to the teenage years, especially around 17.
